Koning "F" Reservoir dam
Koning "F" Reservoir
Koning "F" Reservoir is a privately owned irrigation reservoir located in Polk, Oregon. Built in 1995, this Earth dam stands at a height of 23 feet and has a length of 600 feet, providing a storage capacity of 99 acre-feet and covering a surface area of 11.8 acres. The reservoir is situated on an unnamed tributary to Ash Swale and serves the primary purpose of irrigation for the surrounding area.
Managed by the Oregon Water Resources Department, Koning "F" Reservoir is regulated, permitted, inspected, and enforced by the state agency. Despite being classified as having a low hazard potential, the reservoir's condition is currently not rated. With a regular inspection frequency of 6 years, the dam's emergency action plan status and risk assessment measures are not specified in the available data. As a critical water resource in the region, Koning "F" Reservoir plays a vital role in supporting agricultural activities and water supply needs in the area.
Located in a remote area with no downstream settlement, Koning "F" Reservoir poses minimal risk to surrounding communities. The dam is not associated with any federal agencies and has not undergone any significant modifications since its completion. With its stable condition and consistent water storage capacity, this reservoir serves as a reliable source of irrigation water for the local agricultural community, contributing to sustainable water resource management in the region.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Koning "F" Reservoir
Where does the data for Koning "F" Reservoir come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
